手元のマシンでは zlib なしで mswin のビルドをしようとするんですが、
下記のように、nmake install で途中で失敗します。

$ nmake install

zlibのサイトにあるDLLとヘッダをインストールして、--with-opt-dirか--with-zlib-dirで指定してください。

そりゃそうなんですが、そもそもzlibがない場合はgemのインストールをスキップするか、またはzlibがなければ死ねばーかばーかとドキュメントで明記するか、どっちかが必要でしょう。

I'm reviewing our Gentoo patches for ruby 2.2.1 and noticed that there is a typo in this patch that causes installation to still fail without zlib:

begin
require "zlib"
rescue LoadErroe
end

This should obviously be "rescue LoadError"
